Mar B Plumbing Corp

What this record tells you

Mar B Plumbing Corp holds Florida licence CFC057729, a CFC classification which authorises work as a certified/registered plumbing contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2000, which makes it one of the longest-held licences for the trade in this area. Roughly 7% of the 1,098 active plumbing licences based in the Miami area were issued earlier than this one, and the local median sits at 2022. That is 26 years of continuous licensure.

Mar B Plumbing Corp is one of 5 active plumbing licences registered to an address in Key Biscayne, so you have local alternatives to compare quotes against. Silvio Martinez additionally holds 1 other active Florida licence in our records, which can indicate a contractor qualified across more than one trade or entity.

The licence is recorded as expiring on 08/31/2026. Florida licences renew on a fixed cycle, and a licence that is not renewed moves to delinquent status — which is why the expiry date matters if you are planning work close to that date. Confirm the current status on the state portal before signing a contract.
